Subject: tools string: Use __fallthrough in perf_atoll()

From: Arnaldo Carvalho de Melo <[email protected]>

commit 94bdd5edb34e472980d1e18b4600d6fb92bd6b0a upstream.

The implicit fall through case label here is intended, so let us inform that to gcc >= 7:

CC /tmp/build/perf/util/string.o
util/string.c: In function 'perf_atoll':
util/string.c:22:7: error: this statement may fall through [-Werror=implicit-fallthrough=]

      if (*p)
         ^
  util/string.c:24:3: note: here
     case '\0':
     ^~~~
